PACKING-RING.

Specification of Letters Patent.

Patented Aug. at, 1914.

Application filed June 21, 1913. Serial No. 774.945.

To all whom it may concern:

Be it known that I, Greener. "W. Owens, a citizen of the United States, residing at the city of St. Louis, State. of Missouri, have invcnted certain new and useful Improvements in Packing-Rings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in packing rings and relates more particularly to packing rings adapted for use on pistons, and the pbject of the invention is to provide a packing ring of novel, improved and economical construetion, which is permitted to freely expand for the purpose of making intimate contact with the cylinder.

view of the preferred or-m of the invention In the drawings: Figure l is a perspective Fig. 2 is a top plan view; Fig. 3 is a side elevation; Fig. -l is a perspective view of a modified form of the inventionyl ig. 5 is a side elevation, partly brokenaway, and in section; Fi 6 is a perspective view oi a further mot ifiedform ofthe invention; Fig. 7 is' a perspective view of a still further modified form of the invention; Fig. -8 is a perspective view of another modified form of the invention; Fig. 9 is a perspective view of a still further modified form of theinvention; Fig. 10 is a side "elevation, partly broken away and in section of Fig. 5'); and Figs. 11, 12, 13, and 14: are cross-sectional views. of four alternate forms of the rings shown in Figs. 9 and 10.

In the form of the invention depicted in Figs. 1 to of the drawings, the ring 1 is formed of a steel band which has an-arcual cut 2 preferably locatedcentrally between the side edges of the ring, which cut may be greater or less than a semi-circle. One end of the cut 2 terminates at the inner end of an inclined cut 3 which latter extends through one of the side edges of the ring, while the opposite end of the cut.2 terminates at the inner end of an inclined cut l,

the latter, however, extending through the side edge of the ring opposite to that through which the inclined cut 3 extends, and also,;being inclined in the opposite direction from the inclination of the cut 3, as depicted in'Fi 's. 1 and 3 of the drawings.

From the a ove it will be seen that the movable and oppo ring has a'pair of freely 5 and 6 which can sitelv disposed end parts .side of the cut 8, the

substantially V-shaped cut 9, that is located move to contact with the cylinder. and which being located adjacent the respective side edges of the ring, insure a more perfect joint between the piston and cylinder. Further, by lo -ating the extremities of the parts 5 and (i at points diametrically opposite to each other, the said parts are thus permitted to freely engage the cylinder at widely separated points. which assures a more perfect joint. and in addition a large major portion 7 is pro vidcd on the ring, which acts to more effectively connect the parts.

in Figs. 4 and 5 of the drawings, the ring is provided with a cut 8 which extends nearly entirely around the band. On one ring isiormcd with a opposite to the uncut portion l0. The ring, on the other side of the cut 8 is formed with an inclined cut ll, which extends inwardly to the cut 8. The inner circumference oi the ring is formed with a cat-away portion 12 am each of the inner side edges of the ring is provided with eut-away portions 13 to reccive the lateral flanges 14 formed on an arcuate spring 15 which latter is employed to expand the ring against the cylinder.

\Vith use of the structure depicted inFigs. it and 5 it will be seen that the ring has three Freely movable parts 16, 1'7 and 18 which con t'ormably engage the cylinder, the spring acting to cover the slotS and thereby pre: vent leakage of steam thcrepast and through the out 9.

In the term of the invention depicted in Fig. 6, the ring has the cut 8, the uncutpart 10, the cut 11, the springlfi, and the cut away parts 12 and 13 which receive the spring 15 and the flanges 14 thereof, all as described in connection with the form of the invention shown in Figs. l and In Fig. 6, however, the side of the ring opposite to the side thathas the inclined cut 11 is formed with a comparatively short cut 19 which extends sithstantiiillyparallel to the tilt 8 and which has oppositely inclined cuts 20 and 21 extending from its ends through,

the side edge of the ring and into the cut 8 respectively, to provide three freely movable and separated portions 22, 23 and 24, which can move to engage with the cylinderand which with the part l8 provide the ring with four freelv movable part-s, instead of the three freely movable parts shown in Figs. 4 and 5. In each of the forms shown ing ring is shown which inldigs. 4, 5 and 6, the spring acts to force lithe said freely movable parts outwardly against the cylinder.

In Fig. 7 of the drawings, the ring is identical with that described in connection with Figs. 4, 5 and 6, with the exception that there are two cuts 8" which extend from the ends of part 10' to the ends of a art 25 which latter is located substantially iametically opposite to the part 10, the ring be ing formed with inclined cuts 26 and 27, which extend from the ends of the part 25 in opposite directions from the latter so that cut 26 extends through one side edge of the ring and c 2? nds through the opposite side edge or the ring, thus providing four freely movable parts 28, 29, 3'0 and 31, which together with the part 18 provide the ring with live freely movable parts.

Referring to the form of the invention shown in Big. 8 of the drawings, it willbc seen that the ring is composed of two members 32 and 33 each in the form of an incomplete circle. The member 32 has a head 34 which extends outwardly from its inner side, the sides of the head being inclined and converging inwardly, while the free ends of the member 33 are inclined so as to and interlock with the head 34. Similarly, the member has a head 36 the sides of which are inclined and converge inwardly free ends 37 of the member It will be apparent Fig. 8 of the drawings, that the heads 34 and 36 extend in opposite directions and are located at points diametrically opposite to each other, whereby the four ends of the members provide as many freely movable parts which can move to engage with the c ylinder. In order to eii'ect outward move ment of the ends of the members, flat springs 38 may be inset or secured to the heads 34. and 36, so that the free ends of the springs bear against the respective free ends of the members to move the said free ends outwardly against the cylinder. From the above it will be readily apparent that the free ends of one member interlock with the head of the other member, whereby the head 36 of member 33 holds the free ends 37 of the member against lateral move ment, and. the head or the member 32 holds the free ends of the member 33 against lateral movement.

In Figs 9 and 10 of the drawings, a packconsists of a pair of members 39 and 40, the member 39 being cutaway on its periphery to form a tongue 41 while the member e10 is cutaway on its inner circumference to form a tongue 42 which engages the tongue 41 whereby an overlapping joint is formed between the two members. If desired, the member 39 may he formed with a tongue that has an inclined and interlock with he inclined from inspection or" I l l inner face 43 which engages the beveled edge al of the member 450, as shown in Fig. 11 of the drawings, or as illustrated in Fig. 12, the member 39 may be formed with'a larger tongue 45 which has an inclined inner face andterminates in a cut-out part dB. The member 4.0 in Fig. 12 has a beveled edge 4-7 which engages the inclined face of tongue 45, and a. tongue which projects into the cut-out part 426. In Fig. 13, the member 39 is formed with a concave groove -19 and a convex tongue 51 which projects into the concave groove 49 and a cut-out part 52 which receives the tongue of member 39.

A still, further form of joint between the.

members 39 and 40 may be a straight one, such as is depicted at 53 in Fig. 14.

In order to hold the two members 39 and 40 in their relative assembled position, against sliding movements, the member 39 is formed with n. projection M which fits in a notch 55 formed in the member 40, as shown in Fig. 9.

Each of the members 39 and 4:0 is formed with a cut 56 located between the side edges of the respective members. Inclined cuts 57 extend from the ends of each of the cuts 56 through the inner and outer sides of the respective members thereby providing each ring with four li eely movable parts or ends 58.
